Description

La présente invention concerne un actionneur électromécanique comprenant un moteur électrique, ainsi qu'une installation domotique de fermeture ou de protection solaire comprenant un tel actionneur, et un procédé de fabrication d'un tel actionneur.The present invention relates to an electromechanical actuator comprising an electric motor, and a home automation system for closing or sun protection comprising such an actuator, and a method of manufacturing such an actuator.

De manière générale, la présente invention concerne le domaine des dispositifs d'occultation comprenant un dispositif d'entraînement motorisé mettant en mouvement un écran entre au moins une première position et une deuxième position.In general, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and a second position.

Un dispositif d'entraînement motorisé comprend un actionneur électromécanique d'un élément mobile de fermeture, d'occultation ou de protection solaire tel qu'un volet, une porte, une grille, un store, ou tout autre matériel équivalent, appelé par la suite écran.A motorized drive device comprises an electromechanical actuator of a movable closure, concealment or sun protection element such as a shutter, a door, a grating, a blind, or any other equivalent material, hereafter called screen.

On connaît déjà le document EP 1 420 502 qui décrit un moteur électrique à courant continu sans balais à commutation électronique comprenant un rotor et un stator positionnés de manière coaxiale autour d'un axe de rotation.We already know the document EP 1 420 502 which discloses an electronically commutated DC brushless DC motor having a rotor and a stator coaxially positioned about an axis of rotation.

Le rotor comprend un arbre de rotor. Une première extrémité de l'arbre de rotor est supportée par un premier palier. Et une deuxième extrémité de l'arbre de rotor est supportée par un deuxième palier.The rotor comprises a rotor shaft. A first end of the rotor shaft is supported by a first bearing. And a second end of the rotor shaft is supported by a second bearing.

Le stator comprend un corps de stator et un noyau de stator. Le corps de stator comprend un premier logement annulaire à l'intérieur duquel est disposé le premier palier, et un deuxième logement annulaire à l'intérieur duquel est disposé le deuxième palier.The stator includes a stator body and a stator core. The stator body comprises a first annular housing inside which is disposed the first bearing, and a second annular housing within which is disposed the second bearing.

Le premier palier comporte un organe de roulement, l'organe de roulement étant un roulement à aiguilles. Le deuxième palier comporte un organe de roulement, l'organe de roulement étant un roulement à billes.The first bearing comprises a rolling member, the rolling member being a needle bearing. The second bearing comprises a rolling member, the rolling member being a ball bearing.

Les premier et deuxième paliers sont montés respectivement avec un ajustement serré dans les premier et deuxième logements annulaires du corps de stator.The first and second bearings are respectively mounted with a tight fit in the first and second annular housing of the stator body.

Cependant, ce moteur électrique présente l'inconvénient de mettre en oeuvre une solution onéreuse au moyen de deux paliers comprenant chacun un organe de roulement.However, this electric motor has the disadvantage of implementing an expensive solution by means of two bearings each comprising a rolling member.

L'utilisation du premier palier en tant que roulement à aiguilles de faible encombrement est également onéreuse.The use of the first bearing as a small-sized needle roller bearing is also expensive.

En outre, le montage du premier palier à l'intérieur du premier logement annulaire du corps de stator est complexe, étant donné que le premier palier est un roulement à aiguilles où la bague extérieure est montée avec un ajustement serré dans le premier logement annulaire du corps de stator.In addition, the mounting of the first bearing within the first annular housing of the stator body is complex, since the first bearing is a needle bearing where the outer ring is mounted with a snug fit in the first annular housing of the stator body.

Par ailleurs, les tolérances d'assemblage des premier et deuxième paliers dans les premier et deuxième logements annulaires du corps de stator, ainsi que les tolérances de dimensionnement des premier et deuxième logements annulaires et de l'arbre de rotor sont précises pour limiter les contraintes sur l'arbre de rotor, ce qui engendre des coûts de fabrication élevés.In addition, the assembly tolerances of the first and second bearings in the first and second annular housings of the stator body, as well as the dimensioning tolerances of the first and second annular housings and the rotor shaft are precise to limit the stresses on the rotor shaft, which generates manufacturing costs high.

Par conséquent, pour limiter les coûts de fabrication, une solution serait d'utiliser des tolérances d'assemblage et de dimensionnement moins précises.Therefore, to limit manufacturing costs, one solution would be to use less precise assembly and sizing tolerances.

Néanmoins, lors de l'entraînement en rotation du rotor, un tel assemblage engendre des vibrations provoquées, notamment, par un palier monté peu serré.However, during the rotational drive of the rotor, such an assembly generates vibrations caused, in particular, by a bearing mounted loosely.

On connaît également le document WO-A-2013/050722 qui décrit un moteur d'un type voisin, qui diffère de celui de EP-A-1 420 502 en ce que, les premier et deuxième paliers sont montés serrés dans des logements prévus dans des pièces rapportées sur le stator et distinctes du corps de stator.The document is also known WO-2013/050722 which describes an engine of a similar type, which differs from that of EP-A-1,420,502 in that the first and second bearings are mounted tight in housings provided in stator inserts and separate from the stator body.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un actionneur électromécanique, une installation domotique de fermeture ou de protection solaire comprenant un tel actionneur, ainsi qu'un procédé de fabrication d'un tel actionneur, permettant d'assembler un rotor et un stator d'un moteur électrique au moyen d'au moins un palier en limitant les vibrations du moteur électrique lors de l'entraînement en rotation de l'arbre de rotor tout en minimisant les coûts de fabrication du moteur électrique d'un actionneur électromécanique, ainsi que les contraintes sur l'arbre de rotor.The object of the present invention is to solve the abovementioned drawbacks and to propose an electromechanical actuator, a home automation system for closing or solar protection comprising such an actuator, as well as a method of manufacturing such an actuator, making it possible to assemble a rotor and a stator of an electric motor by means of at least one bearing by limiting the vibrations of the electric motor during the rotational drive of the rotor shaft while minimizing the manufacturing costs of the electric motor of a electromechanical actuator, as well as the stresses on the rotor shaft.

A cet effet, la présente invention vise, selon un premier aspect, un actionneur électromécanique pour une installation domotique de fermeture ou de protection solaire comprenant un moteur électrique, le moteur électrique comprenant un rotor et un stator positionnés de manière coaxiale autour d'un axe de rotation,

  • où le rotor comprend un arbre de rotor, l'arbre de rotor comportant une extrémité supportée par un palier,
  • où le stator comprend un noyau de stator et un corps de stator, le corps de stator comprenant un logement annulaire à l'intérieur duquel est disposé le palier.
For this purpose, the present invention aims, in a first aspect, an electromechanical actuator for a home automation system for closing or sun protection comprising an electric motor, the electric motor comprising a rotor and a stator coaxially positioned around an axis of rotation,
  • wherein the rotor comprises a rotor shaft, the rotor shaft having an end supported by a bearing,
  • wherein the stator comprises a stator core and a stator body, the stator body including an annular housing within which the bearing is disposed.

Selon l'invention, le palier est monté avec un ajustement libre à l'intérieur du logement annulaire du corps de stator, l'ajustement libre étant défini par un premier jeu de fonctionnement axial, ce premier jeu de fonctionnement axial étant réalisé par une différence entre, d'une part, une longueur axiale, mesurée le long de l'axe de rotation, entre une première butée et une deuxième butée du logement annulaire du corps de stator et, d'autre part, une longueur axiale du palier, et un deuxième jeu de fonctionnement radial, le deuxième jeu de fonctionnement radial étant réalisé entre une surface annulaire externe du palier et la surface annulaire du logement annulaire du corps de stator. Un joint élastique annulaire est disposé autour du palier, le joint élastique annulaire étant comprimé entre la surface annulaire du logement annulaire du corps de stator et une surface annulaire externe du palier. Et la première butée du logement annulaire du corps de stator est formée par déformation plastique du corps de stator.According to the invention, the bearing is mounted with a free fit inside the annular housing of the stator body, the free adjustment being defined by a first set of axial operation, this first set of axial operation being realized by a difference between, on the one hand, an axial length, measured along the axis of rotation, between a first abutment and a second abutment of the annular housing of the stator body and, on the other hand, an axial length of the bearing, and a second radial operating clearance, the second radial operating clearance being formed between a outer annular surface of the bearing and the annular surface of the annular housing of the stator body. An annular elastic seal is disposed around the bearing, the annular resilient seal being compressed between the annular surface of the annular housing of the stator body and an outer annular surface of the bearing. And the first abutment of the annular housing of the stator body is formed by plastic deformation of the stator body.

Ainsi, l'actionneur électromécanique comprend un moteur électrique pourvu d'un stator à l'intérieur duquel est mis en rotation un rotor, où le rotor comporte un arbre de rotor supporté par un palier, et où un joint élastique annulaire est monté entre le palier et le logement annulaire recevant le palier, de sorte à limiter les vibrations du moteur électrique lors de l'entraînement en rotation de l'arbre de rotor et à corriger l'alignement de l'arbre de rotor à l'intérieur du corps de stator tout en minimisant les coûts de fabrication du moteur électrique d'un actionneur électromécanique.Thus, the electromechanical actuator comprises an electric motor provided with a stator inside which is rotated a rotor, wherein the rotor comprises a rotor shaft supported by a bearing, and where an annular elastic seal is mounted between the bearing and the annular housing receiving the bearing, so as to limit the vibrations of the electric motor during the rotary drive of the rotor shaft and to correct the alignment of the rotor shaft inside the body of stator while minimizing the manufacturing costs of the electric motor of an electromechanical actuator.

De cette manière, le moteur électrique comprend ainsi un logement annulaire du corps de stator à l'intérieur duquel est inséré un palier, où le palier présente des dimensions lui permettant d'être mobile suivant les directions axiale et radiale à l'intérieur du logement annulaire du corps de stator.In this way, the electric motor thus comprises an annular housing of the stator body inside which is inserted a bearing, where the bearing has dimensions allowing it to be movable in the axial and radial directions inside the housing. annular of the stator body.

En outre, le joint élastique annulaire permet d'amortir la transmission de vibrations entre l'arbre de rotor et le stator, ainsi qu'avec un arbre de sortie du moteur électrique.In addition, the annular elastic seal dampens the transmission of vibrations between the rotor shaft and the stator, as well as with an output shaft of the electric motor.

De cette manière, l'amortissement des vibrations au moyen du joint élastique annulaire permet de limiter l'usure des éléments constituant l'actionneur électromécanique et de minimiser le bruit engendré par des vibrations au niveau de l'installation domotique.In this way, the damping of the vibrations by means of the annular elastic seal makes it possible to limit the wear of the elements constituting the electromechanical actuator and to minimize the noise generated by vibrations at the level of the home automation installation.

En outre, le joint élastique annulaire permet de corriger l'alignement entre l'arbre de rotor et le corps de stator.In addition, the annular elastic seal makes it possible to correct the alignment between the rotor shaft and the stator body.

De cette manière, la correction de l'alignement de l'arbre de rotor au moyen du joint élastique annulaire permet également de limiter l'usure des éléments constituant l'actionneur électromécanique et de minimiser le bruit engendré par des vibrations au niveau de l'installation domotique.In this way, the correction of the alignment of the rotor shaft by means of the annular elastic seal also makes it possible to limit the wear of the elements constituting the electromechanical actuator and to minimize the noise generated by vibrations at the level of the rotor. home automation system.

Le joint élastique annulaire monté autour du palier permet de réaliser une liaison de type rotule ente l'arbre de rotor et le logement annulaire du corps de stator.The annular elastic seal mounted around the bearing makes it possible to make a connection of the ball-and-socket type between the rotor shaft and the annular housing of the stator body.

Ainsi, le joint élastique annulaire monté autour du palier permet à l'arbre de rotor d'être mobile en rotation autour de l'axe de rotation du moteur électrique.Thus, the annular elastic seal mounted around the bearing allows the rotor shaft to be rotatable about the axis of rotation of the electric motor.

Par ailleurs, la première butée du logement annulaire du corps de stator est réalisée de manière simple, rapide et peu onéreuse.In addition, the first abutment of the annular housing of the stator body is made simply, quickly and inexpensively.

L'introduction d'un outil à l'intérieur du corps du stator permet de former aisément la première butée suite à l'introduction du palier dans le logement annulaire du corps de stator.The introduction of a tool inside the stator body makes it easy to form the first stop after the introduction of the bearing in the annular housing of the stator body.

Un tel assemblage permet également de diminuer la précision des tolérances des éléments constituant le moteur électrique, en particulier au niveau du stator et du rotor, de sorte à diminuer le coût d'obtention de celui-ci.Such an assembly also makes it possible to reduce the accuracy of the tolerances of the elements constituting the electric motor, in particular at the level of the stator and of the rotor, so as to reduce the cost of obtaining it.

Pratiquement, le corps du stator est réalisé en matière plastique.Practically, the stator body is made of plastic.

Avantageusement, la deuxième butée du logement annulaire du corps de stator est formée par une paroi d'extrémité du logement annulaire du corps de stator.Advantageously, the second abutment of the annular housing of the stator body is formed by an end wall of the annular housing of the stator body.

Préférentiellement, le joint élastique annulaire monté autour du palier est disposé entre un épaulement du palier et une face frontale d'extrémité du palier.Preferably, the annular elastic seal mounted around the bearing is disposed between a shoulder of the bearing and a front end face of the bearing.

Avantageusement, la première butée du logement annulaire du corps de stator coopère avec un épaulement du palier.Advantageously, the first abutment of the annular housing of the stator body cooperates with a shoulder of the bearing.

Dans un mode de réalisation, l'arbre de rotor comporte une autre extrémité supportée par un autre palier, l'autre palier comportant un organe de roulement, alors qu'un support comprend un autre logement annulaire à l'intérieur duquel est disposé l'autre palier, le support étant relié au corps de stator.In one embodiment, the rotor shaft has another end supported by another bearing, the other bearing comprising a rolling member, while a support comprises another annular housing inside which is disposed the another bearing, the support being connected to the stator body.

Avantageusement, le joint élastique annulaire est monté autour du palier avec un ajustement libre.Advantageously, the annular elastic seal is mounted around the bearing with a free fit.

Selon une caractéristique préférée de l'invention, le palier comprend au moins un élément de positionnement angulaire coopérant avec une encoche du corps de stator.According to a preferred characteristic of the invention, the bearing comprises at least one angular positioning element cooperating with a notch of the stator body.

L'actionneur 11 comprend un moteur électrique 12. Le moteur 12 comprend un rotor 13 et un stator 14 positionnés de manière coaxiale autour d'un axe de rotation X.The actuator 11 comprises an electric motor 12. The motor 12 comprises a rotor 13 and a stator 14 positioned coaxially about an axis of rotation X.

Le rotor 13 comprend un corps de rotor 15 muni d'éléments magnétiques 16 entourés par le stator 14. Les éléments magnétiques 16 constituent des paires de pôles.The rotor 13 comprises a rotor body 15 provided with magnetic elements 16 surrounded by the stator 14. The magnetic elements 16 constitute pairs of poles.

Avantageusement, les éléments magnétiques 16 sont disposés sur la circonférence extérieure du corps de rotor 15. Les éléments magnétiques 16 du rotor 13 constituent un aimant permanent.Advantageously, the magnetic elements 16 are arranged on the outer circumference of the rotor body 15. The magnetic elements 16 of the rotor 13 constitute a permanent magnet.

Ainsi, l'aimant permanent formé par les éléments magnétiques 16 entoure le corps de rotor 15. L'aimant permanent est séparé du stator 14 par un entrefer 25, radial par rapport à l'axe de rotation X.Thus, the permanent magnet formed by the magnetic elements 16 surrounds the rotor body 15. The permanent magnet is separated from the stator 14 by an air gap 25, radial with respect to the axis of rotation X.

Les éléments magnétiques 16 séparés constituant l'aimant permanent peuvent être rapportés sur la circonférence extérieure du corps de rotor 15 par collage, surmoulage ou toute autre technique connue.The separate magnetic elements 16 constituting the permanent magnet can be reported on the outer circumference of the rotor body 15 by gluing, overmolding or any other known technique.

Le stator 14 est formé par un noyau de stator 17 comprenant des éléments polaires 28 répartis sur la périphérie du stator 14, préférentiellement sur la périphérie extérieure du stator 14.The stator 14 is formed by a stator core 17 comprising polar elements 28 distributed on the periphery of the stator 14, preferably on the outer periphery of the stator 14.

Le stator 14 comprend également un corps de stator 18.The stator 14 also comprises a stator body 18.

Le corps de rotor 15 est relié solidairement en rotation à un arbre de rotor 24. L'arbre de rotor 24 est centré sur l'axe de rotation X et dépasse de part et d'autre du corps de rotor 15.The rotor body 15 is integrally connected in rotation to a rotor shaft 24. The rotor shaft 24 is centered on the axis of rotation X and protrudes on either side of the rotor body 15.

Ainsi, l'arbre de rotor 24 comprend une première et une deuxième extrémités 24a, 24b en saillie par rapport au corps de rotor 15.Thus, the rotor shaft 24 comprises first and second ends 24a, 24b projecting from the rotor body 15.

Ici, le moteur électrique 12 est de type à courant continu sans balais à commutation électronique.Here, the electric motor 12 is of the DC brushless direct current type.

Avantageusement, le corps de rotor 15 est formé à partir d'un empilage de tôle.Advantageously, the rotor body 15 is formed from a sheet stack.

Dans un autre mode de réalisation, le corps de rotor 15 est réalisé par un arbre massif.In another embodiment, the rotor body 15 is made of a solid shaft.

Le stator 14 définit un espace interne E cylindrique à section circulaire dans lequel le rotor 13, y compris notamment les éléments magnétiques 16, est positionné, et à l'intérieur duquel le rotor 13 est en rotation lorsque le moteur 12 fonctionne.The stator 14 defines a cylindrical internal space E with a circular section in which the rotor 13, including in particular the magnetic elements 16, is positioned, and inside which the rotor 13 is rotated when the motor 12 is operating.

Le diamètre de l'espace cylindrique E est tel que cet espace E reçoit le rotor 13 ainsi que les éléments magnétiques 16. La partie magnétique ou magnétisée du rotor 13 se trouvant à l'intérieur de l'espace cylindrique E interne au stator 14, le rotor 13 est qualifié de rotor interne.The diameter of the cylindrical space E is such that this space E receives the rotor 13 as well as the magnetic elements 16. The magnetic or magnetized part of the rotor 13 located inside the cylindrical space E inside the stator 14, the rotor 13 is called internal rotor.

L'espace cylindrique E reçoit également un premier palier 26 et un deuxième palier 27 de support en rotation de l'arbre de rotor 24.The cylindrical space E also receives a first bearing 26 and a second bearing 27 for supporting rotation of the rotor shaft 24.

Ainsi, l'arbre de rotor 24 est monté en rotation au niveau de ses deux extrémités 24a et 24b par l'intermédiaire des deux paliers 26, 27.Thus, the rotor shaft 24 is rotatably mounted at its two ends 24a and 24b via the two bearings 26, 27.

Ici, la première extrémité 24a de l'arbre de rotor 24 est supportée par le premier palier 26, tandis que la deuxième extrémité 24b de l'arbre de rotor 24 est supportée par le deuxième palier 27.Here, the first end 24a of the rotor shaft 24 is supported by the first bearing 26, while the second end 24b of the rotor shaft 24 is supported by the second bearing 27.

Les premier et deuxième paliers 26, 27 sont ainsi positionnés de part et d'autre du corps de rotor 15 suivant l'axe de rotation X.The first and second bearings 26, 27 are thus positioned on either side of the rotor body 15 along the axis of rotation X.

Ici et tel qu'illustré aux figures 3, 4 et 7, le premier palier 26 est un palier lisse, ou communément appelé coussinet, et de préférence réalisé dans un matériau autolubrifiant.Here and as illustrated in figures 3 , 4 and 7 , the first bearing 26 is a plain bearing, or commonly called bearing, and preferably made of a self-lubricating material.

Le premier palier 26 est une pièce de révolution, et en particulier de forme cylindrique. Le premier palier comprend deux faces d'extrémité 26a, 26b, ces faces d'extrémité 26a, 26b étant orthogonales à l'axe de rotation X. Le premier palier 26 comprend également deux épaulements 26c, 26d, ces deux épaulements 26c, 26d étant disposés respectivement entre les deux faces d'extrémités 26a, 26b.The first bearing 26 is a part of revolution, and in particular of cylindrical shape. The first bearing comprises two end faces 26a, 26b, these end faces 26a, 26b being orthogonal to the axis of rotation X. The first bearing 26 also comprises two shoulders 26c, 26d, these two shoulders 26c, 26d being disposed respectively between the two end faces 26a, 26b.

Ici, l'arbre de rotor 24, en particulier la première extrémité 24a de l'arbre de rotor 24, traverse le premier palier 26.Here, the rotor shaft 24, in particular the first end 24a of the rotor shaft 24, passes through the first bearing 26.

Le deuxième palier 27 comporte un organe de roulement monté avec un ajustement serré dans un deuxième logement annulaire 36 d'un support 39. Le support 39 est relié au corps de stator 18.The second bearing 27 comprises a rolling member mounted with a tight fit in a second annular housing 36 of a support 39. The support 39 is connected to the stator body 18.

Ici, et tel qu'illustré aux figures 3, 4 et 7, le deuxième palier 27 est un roulement à billes.Here, and as illustrated in figures 3 , 4 and 7 the second bearing 27 is a ball bearing.

Un noyau central est ici formé par le noyau de stator 17 appartenant au stator 14. Le noyau de stator 17 est en matériau magnétisable et plus spécifiquement en matériau ferromagnétique. Il est généralement formé par un empilage de tôles et muni de garnitures isolantes.A central core is here formed by the stator core 17 belonging to the stator 14. The stator core 17 is made of magnetizable material and more specifically of ferromagnetic material. It is generally formed by a stack of sheets and provided with insulating fittings.

Les éléments polaires 28 du noyau 17 sont en saillie, radialement vers l'extérieur du moteur électrique 12, par rapport à l'axe de rotation X.The pole elements 28 of the core 17 protrude radially outwardly from the electric motor 12 relative to the axis of rotation X.

Des bobinages 29 sont positionnés autour des éléments polaires 28 du stator 14.Windings 29 are positioned around the pole elements 28 of the stator 14.

Plus précisément, chaque élément polaire 28 est entouré par un bobinage 29 qui lui est propre. Les bobinages 29 sont reliés de sorte que, lorsqu'ils sont parcourus par un courant, ils produisent un champ magnétique tournant qui entraîne en rotation le rotor 13. Les bobinages 29 sont isolés du noyau de stator 17, en particulier par le corps de stator 18. Pour la clarté du dessin, ces bobinages ne sont pas représentés à la figure 6.More specifically, each polar element 28 is surrounded by a winding 29 which is specific to it. The coils 29 are connected so that, when traversed by a current, they produce a rotating magnetic field which rotates the rotor 13. The coils 29 are isolated from the stator core 17, in particular by the stator body 18. For the sake of clarity, these windings are not shown in the figure 6 .

Le stator 14 comprend, sur sa circonférence extérieure, une culasse 30. La culasse 30 entoure le stator 14, c'est-à-dire le noyau central 17, qui est propre à la recevoir, et est centrée sur l'axe de rotation X. Cette culasse 30 permet la circulation du flux magnétique.The stator 14 comprises, on its outer circumference, a yoke 30. The yoke 30 surrounds the stator 14, that is to say the central core 17, which is adapted to receive it, and is centered on the axis of rotation X. This yoke 30 allows the circulation of the magnetic flux.

Le corps de stator 18 comprend un premier logement annulaire 32 à l'intérieur duquel est disposé le premier palier 26.The stator body 18 comprises a first annular housing 32 inside which the first bearing 26 is disposed.

Ici, le corps de stator 18 est réalisé en matière plastique, et en particulier par une opération de surmoulage du noyau de stator 17. Le premier logement annulaire 32 fait partie du corps de stator 18.Here, the stator body 18 is made of plastic material, and in particular by an overmolding operation of the stator core 17. The first annular housing 32 is part of the stator body 18.

Le corps de stator 18 est relié au support 39, en particulier au moyen d'éléments d'encliquetage élastique.The stator body 18 is connected to the support 39, in particular by means of elastic detent elements.

Ici, le support 39 comprend le deuxième logement annulaire 36 à l'intérieur duquel est disposé le deuxième palier 27.Here, the support 39 comprises the second annular housing 36 inside which the second bearing 27 is disposed.

Dans un autre mode de réalisation non illustré, le deuxième logement annulaire 36 recevant le deuxième palier 27 est réalisé dans le corps de stator 18.In another embodiment not illustrated, the second annular housing 36 receiving the second bearing 27 is formed in the stator body 18.

Le premier palier 26 est monté avec un ajustement libre à l'intérieur du premier logement annulaire 32 du corps de stator 18, cet ajustement libre comportant un premier jeu de fonctionnement axial J1 et un deuxième jeu de fonctionnement radial J2, tel qu'illustré à la figure 5.The first bearing 26 is mounted with a free fit inside the first annular housing 32 of the stator body 18, this free fit having a first axial operating clearance J1 and a second radial operating clearance J2, as illustrated in FIG. the figure 5 .

Le premier jeu de fonctionnement axial J1 est réalisé par une différence entre, d'une part, une longueur axiale L32 mesurée le long de l'axe de rotation X, entre une première butée 33 et une deuxième butée 34 du premier logement annulaire 32 du corps de stator 18, et d'autre part, une longueur axiale L26 du premier palier 26, mesurée le long de cet axe de rotation X.The first axial operating clearance J1 is produced by a difference between, on the one hand, an axial length L32 measured along the axis of rotation X, between a first stop 33 and a second stop 34 of the first annular housing 32 of the stator body 18, and secondly, an axial length L26 of the first bearing 26, measured along this axis of rotation X.

Et le deuxième jeu de fonctionnement radial J2 est réalisé entre une surface annulaire externe 26f du premier palier 26 et la surface annulaire 32f du premier logement annulaire 32 du corps de stator 15.And the second radial operating clearance J2 is formed between an outer annular surface 26f of the first bearing 26 and the annular surface 32f of the first annular housing 32 of the stator body 15.

A titre d'exemple nullement limitatif, le premier jeu de fonctionnement axial J1 est de l'ordre de 0,1 à 0,4 millimètres, et le deuxième jeu de fonctionnement radial J2 est de l'ordre de 0,1 à 0,3 millimètres.By way of non-limiting example, the first axial operating clearance J1 is of the order of 0.1 to 0.4 millimeters, and the second radial operating clearance J2 is of the order of 0.1 to 0, 3 millimeters.

Le diamètre externe le plus grand du premier palier 26 est inférieur au diamètre interne du premier logement annulaire 32 du corps de stator 18.The largest outer diameter of the first bearing 26 is smaller than the inner diameter of the first annular housing 32 of the stator body 18.

Ici, et tel qu'illustré à la figure 5, la partie de diamètre externe le plus grand du premier palier 26 est disposé entre les deux épaulements 26c, 26d du premier palier 26.Here, and as illustrated in figure 5 the largest outer diameter portion of the first bearing 26 is disposed between the two shoulders 26c, 26d of the first bearing 26.

Le premier palier 26 est ainsi disposé à l'intérieur du premier logement annulaire 32 de sorte à entourer celui-ci de manière périphérique selon une direction axiale et une direction radiale.The first bearing 26 is thus disposed inside the first annular housing 32 so as to surround it peripherally in an axial direction and a radial direction.

Le corps de stator 18 comprend ainsi un premier logement annulaire 32 à l'intérieur duquel est inséré un premier palier 26, où le premier palier 26 présente des dimensions lui permettant d'être mobile suivant les directions axiale et radiale à l'intérieur du premier logement annulaire 32.The stator body 18 thus comprises a first annular housing 32 inside which is inserted a first bearing 26, where the first bearing 26 has dimensions allowing it to be movable in the axial and radial directions inside the first annular housing 32.

Ici, le premier logement annulaire 32 à l'intérieur duquel est disposé le premier palier 26 est réalisé en un seul tenant lors de la fabrication du corps de stator 18. Et la deuxième butée 34 du premier logement annulaire 32 du corps de stator 18 est réalisée lors de la fabrication du corps de stator 18.Here, the first annular housing 32 inside which is disposed the first bearing 26 is made in one piece during the manufacture of the stator body 18. And the second stop 34 of the first annular housing 32 of the stator body 18 is performed during the manufacture of the stator body 18.

Dans ce mode de réalisation, le premier palier 26 comprend une première face 26e coopérant avec la première butée 33 du premier logement annulaire 32 du corps de stator 18, et une deuxième face 26a, opposée à la première face 26e, coopérant avec la deuxième butée 34 du premier logement annulaire 32 du corps de stator 18.In this embodiment, the first bearing 26 comprises a first face 26e cooperating with the first stop 33 of the first annular housing 32 of the stator body 18, and a second face 26a, opposite the first face 26e, cooperating with the second stop 34 of the first annular housing 32 of the stator body 18.

Ici, et tel qu'illustré à la figure 5, la première face 26e du premier palier 26 est réalisée par le deuxième épaulement 26d. Et la deuxième face 26a du premier palier 26 est une face frontale à une extrémité.Here, and as illustrated in figure 5 , the first face 26 of the first bearing 26 is formed by the second shoulder 26d. And the second face 26a of the first bearing 26 is a front face at one end.

Un joint élastique annulaire 35 est disposé autour du premier palier 26.An annular elastic seal 35 is disposed around the first bearing 26.

Le joint élastique annulaire 35 est comprimé entre la surface annulaire 32f du premier logement annulaire 32 du corps de stator 18 et une surface annulaire externe 26g du premier palier 26.The annular elastic seal 35 is compressed between the annular surface 32f of the first annular housing 32 of the stator body 18 and an outer annular surface 26g of the first bearing 26.

Ainsi, le joint élastique annulaire 35 permet d'amortir la transmission de vibrations entre l'arbre de rotor 24 et le stator 14, ainsi qu'avec un arbre de sortie du moteur électrique 12.Thus, the annular elastic seal 35 damps the transmission of vibrations between the rotor shaft 24 and the stator 14, as well as with an output shaft of the electric motor 12.

De cette manière, l'amortissement des vibrations au moyen du joint élastique annulaire 35 permet de limiter l'usure des éléments constituant l'actionneur électromécanique 11 et de minimiser le bruit engendré par des vibrations au niveau du dispositif d'occultation 3 de l'installation domotique.In this way, the damping of the vibrations by means of the annular elastic seal 35 makes it possible to limit the wear of the elements constituting the electromechanical actuator 11 and to minimize the noise generated by vibrations at the occulting device 3 of the home automation system.

En outre, le joint élastique annulaire 35 permet de corriger l'alignement entre l'arbre de rotor 24 et le corps de stator 18.In addition, the annular elastic seal 35 makes it possible to correct the alignment between the rotor shaft 24 and the stator body 18.

De cette manière, la correction de l'alignement de l'arbre de rotor 24 au moyen du joint élastique annulaire 35 permet également de limiter l'usure des éléments constituant l'actionneur électromécanique 11 et de minimiser le bruit engendré par des vibrations au niveau du dispositif d'occultation 3 de l'installation domotique.In this way, the correction of the alignment of the rotor shaft 24 by means of the annular elastic seal 35 also makes it possible to limit the wear of the elements constituting the electromechanical actuator 11 and to minimize the noise generated by vibrations at the level of the electromechanical actuator 11. occultation device 3 of the home automation system.

Le joint élastique annulaire 35 monté autour du premier palier 26 permet de réaliser une liaison de type rotule ente l'arbre de rotor 24 et le premier logement annulaire 32 du corps de stator 18.The annular elastic seal 35 mounted around the first bearing 26 allows making a ball-type connection between the rotor shaft 24 and the first annular housing 32 of the stator body 18.

Ainsi, le joint élastique annulaire 35 monté autour du premier palier 26 permet à l'arbre de rotor 24 d'être mobile en rotation autour d'un axe Y perpendiculaire à l'axe de rotation X et sécant avec celui-ci.Thus, the annular elastic seal 35 mounted around the first bearing 26 allows the rotor shaft 24 to be rotatable about an axis Y perpendicular to the axis of rotation X and intersecting therewith.

Par ailleurs, grâce au montage du premier palier 26 avec le joint élastique annulaire 35 à l'intérieur du premier logement annulaire 32 et à l'insertion de la première extrémité 24a de l'arbre de rotor 24 dans le premier palier 26, le deuxième palier 27 comprenant un organe de roulement peut être pourvu d'une bague intérieure à jeu de fonctionnement interne réduit, la bague intérieure du deuxième palier 27 coopérant avec la deuxième extrémité 24b de l'arbre de rotor 24.Moreover, by mounting the first bearing 26 with the annular elastic seal 35 inside the first annular housing 32 and the insertion of the first end 24a of the rotor shaft 24 into the first bearing 26, the second bearing 27 comprising a rolling member may be provided with an internal ring with a reduced internal operating clearance, the inner ring of the second bearing 27 cooperating with the second end 24b of the rotor shaft 24.

Ainsi, l'utilisation d'un deuxième palier 27 comprenant une bague intérieure avec un jeu de fonctionnement interne réduit permet de minimiser le bruit de fonctionnement du moteur électrique 12, lors de l'entraînement en rotation du rotor 13 à l'intérieur du stator 14, en évitant des vibrations liées à un débattement de la deuxième extrémité 24b de l'arbre de rotor 24 à l'intérieur du deuxième palier 27.Thus, the use of a second bearing 27 comprising an inner ring with a reduced internal operating clearance makes it possible to minimize the operating noise of the electric motor 12 during the rotational driving of the rotor 13 inside the stator 14, avoiding vibrations related to a displacement of the second end 24b of the rotor shaft 24 inside the second bearing 27.

En outre, l'utilisation d'un deuxième palier 27 comprenant une bague intérieure avec un jeu de fonctionnement interne réduit permet de réduire le coût d'obtention du moteur électrique 12.In addition, the use of a second bearing 27 comprising an inner ring with a reduced internal operating clearance reduces the cost of obtaining the electric motor 12.

Ici, le joint élastique annulaire 35 est un joint torique, et de préférence réalisé en élastomère, notamment en caoutchouc.Here, the annular elastic seal 35 is an O-ring, and preferably made of elastomer, especially rubber.

Dans un mode de réalisation, le joint élastique annulaire 35 présente une section droite de forme circulaire.In one embodiment, the annular elastic seal 35 has a circular cross section.

Bien entendu, la forme de la section du joint élastique annulaire 35 n'est nullement limitative, et peut être différente, et en particulier ovale ou carrée.Of course, the shape of the section of the annular elastic seal 35 is in no way limiting, and may be different, and in particular oval or square.

Ici, et tel qu'illustré aux figures 3 à 5, le joint élastique annulaire 35 monté autour du premier palier 26 est disposé entre le premier épaulement 26c du premier palier 26 et la face frontale d'extrémité 26a du premier palier 26.Here, and as illustrated in Figures 3 to 5 the annular elastic seal 35 mounted around the first bearing 26 is disposed between the first shoulder 26c of the first bearing 26 and the end face 26a of the first bearing 26.

Ainsi, le premier épaulement 26c du premier palier 26 permet de limiter la course de déplacement du joint élastique annulaire 35 le long du premier palier 26 lors de l'introduction du premier palier 26 à l'intérieur du premier logement annulaire 32.Thus, the first shoulder 26c of the first bearing 26 limits the travel of the annular elastic seal 35 along the first bearing 26 during the introduction of the first bearing 26 inside the first annular housing 32.

En outre, le premier épaulement 26c du premier palier 26 forme un logement de retenue du joint élastique annulaire 35.In addition, the first shoulder 26c of the first bearing 26 forms a housing for retaining the annular elastic seal 35.

De cette manière, le logement de retenue du joint élastique annulaire 35 formé dans le premier palier 26 est réalisé de manière simple et peu onéreuse.In this way, the retaining housing of the annular elastic seal 35 formed in the first bearing 26 is made simply and inexpensively.

Par ailleurs, le premier épaulement 26c du premier palier 26 permet d'éviter le retrait du joint élastique annulaire 35, d'une part lié au jeu de fonctionnement axial J1 du premier palier 26 à l'intérieur du premier logement annulaire 32 du corps de stator 18, et d'autre part lié au jeu de fonctionnement radial J2 du premier palier 26 à l'intérieur du premier logement annulaire 32 du corps de stator 18.Furthermore, the first shoulder 26c of the first bearing 26 makes it possible to avoid the withdrawal of the annular elastic seal 35, on the one hand linked to the axial operating clearance J1 of the first bearing 26 inside the first annular housing 32 of the body of stator 18, and secondly related to the radial operating clearance J2 of the first bearing 26 inside the first annular housing 32 of the stator body 18.

Avantageusement, le diamètre de la section droite du joint élastique annulaire 35 est supérieur au jeu de fonctionnement axial J1 réalisé entre la deuxième face 26a du premier palier 26 et la deuxième butée 34 du premier logement annulaire 32 du corps de stator 18 de sorte à éviter le retrait du joint élastique annulaire 35 par rapport au premier épaulement 26c du premier palier 26.Advantageously, the diameter of the cross section of the annular elastic seal 35 is greater than the axial operating clearance J1 formed between the second face 26a of the first bearing 26 and the second stop 34 of the first annular housing 32 of the stator body 18 so as to avoid withdrawing the annular elastic seal 35 relative to the first shoulder 26c of the first bearing 26.

Pratiquement, la partie du corps du premier palier 26 coopérant avec le joint élastique annulaire 35 est lisse, et en particulier de forme cylindrique.Practically, the part of the body of the first bearing 26 cooperating with the annular elastic seal 35 is smooth, and in particular of cylindrical shape.

Avantageusement, le joint élastique annulaire 35 est monté autour du premier palier 26 avec un ajustement libre.Advantageously, the annular elastic seal 35 is mounted around the first bearing 26 with a free fit.

Ainsi, l'assemblage du joint élastique annulaire 35 avec le premier palier 26 n'engendre aucune contrainte sur le joint élastique annulaire 35.Thus, the assembly of the annular elastic seal 35 with the first bearing 26 does not generate any stress on the annular elastic seal 35.

De cette manière, le joint élastique annulaire 35 est comprimé uniquement entre la surface annulaire 32f du premier logement annulaire 32 du corps de stator 18 et la surface annulaire externe 26g du premier palier 26 suite à l'insertion de l'ensemble formé par le joint élastique annulaire 35 et le premier palier 26 dans le premier logement annulaire 32 du corps de stator 18.In this way, the annular elastic seal 35 is compressed only between the annular surface 32f of the first annular housing 32 of the stator body 18 and the outer annular surface 26g of the first bearing 26 following the insertion of the assembly formed by the joint annular resilient 35 and the first bearing 26 in the first annular housing 32 of the stator body 18.

Par conséquent, l'élasticité du joint élastique annulaire 35 est utilisée en totalité pour limiter les vibrations du moteur électrique 12 lors de l'entraînement en rotation de l'arbre de rotor 24 et pour corriger l'alignement de l'arbre de rotor 24 à l'intérieur du corps de stator 18.Therefore, the elasticity of the annular elastic seal 35 is used in its entirety to limit the vibrations of the electric motor 12 during the rotary drive of the rotor shaft 24 and to correct the alignment of the rotor shaft 24 inside the stator body 18.

La première butée 33 du premier logement annulaire 32 du corps de stator 18 est formée par déformation plastique du corps de stator 18, suite à l'introduction du premier palier 26 à l'intérieur du premier logement annulaire 32 du corps de stator 18.The first stop 33 of the first annular housing 32 of the stator body 18 is formed by plastic deformation of the stator body 18, following the introduction of the first bearing 26 into the first annular housing 32 of the stator body 18.

Ainsi, la première butée 33 du premier logement annulaire 32 du corps de stator 18 est réalisée de manière simple, rapide et peu onéreuse.Thus, the first stop 33 of the first annular housing 32 of the stator body 18 is made simply, quickly and inexpensively.

L'introduction d'un outil à l'intérieur du corps du stator 18 permet de former aisément la première butée 33 suite à l'introduction du palier 26 dans le premier logement annulaire 32 du corps de stator 18.The introduction of a tool inside the body of the stator 18 makes it easy to form the first stop 33 following the introduction of the bearing 26 in the first annular housing 32 of the stator body 18.

Ici, la déformation plastique du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18 est réalisée dans quatre zones de déformation 40, de préférence uniformément réparties autour de l'axe de rotation X, comme visible à la figure 6.Here, the plastic deformation of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18 is carried out in four zones of deformation 40, preferably uniformly distributed around the axis of rotation X, as visible in FIG. figure 6 .

Bien entendu, le nombre de zones de déformation du corps de stator formant la première butée du premier logement annulaire du corps de stator n'est nullement limitatif, et peut être différent, en particulier au moins de trois.Of course, the number of deformation zones of the stator body forming the first stop of the first annular housing of the stator body is not limiting, and may be different, in particular at least three.

Les zones de déformation 40 du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18 sont formées sur la circonférence intérieure du corps de stator 18.The deformation zones 40 of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18 are formed on the inner circumference of the stator body 18.

Ainsi, la première face 26e du premier palier 26 réalisée par le deuxième épaulement 26d peut prendre appui contre les zones de déformation 40 du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18.Thus, the first face 26e of the first bearing 26 produced by the second shoulder 26d can bear against the deformation zones 40 of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18.

Ici, les zones de déformation 40 du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18 sont des zones de déformation locales.Here, the deformation zones 40 of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18 are local deformation zones.

Pratiquement, la déformation plastique du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18 correspond à la formation d'une pluralité de saillies de matière du corps de stator 18, les saillies dépassant le diamètre extérieur du premier palier 26 en direction de l'axe de rotation X, de sorte à diminuer localement le diamètre du premier logement annulaire 32 du corps de stator 18.Practically, the plastic deformation of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18 corresponds to the formation of a plurality of material projections of the stator body 18, the projections exceeding the outer diameter of the stator body 18. first bearing 26 in the direction of the axis of rotation X, so as to decrease locally the diameter of the first annular housing 32 of the stator body 18.

Ainsi, les saillies constituant la première butée 33 du premier logement annulaire 32 du corps de stator 18 permettent d'empêcher le retrait du premier palier 26 du premier logement annulaire 32 du corps de stator 18 suivant une direction axiale.Thus, the projections constituting the first stop 33 of the first annular housing 32 of the stator body 18 make it possible to prevent the first bearing 26 from being withdrawn from the first annular housing 32 of the stator body 18 in an axial direction.

En outre, la déformation plastique du corps de stator 18 formant la première butée 33 du premier logement annulaire 32 du corps de stator 18 permet de garantir le maintien du joint élastique annulaire 35 sur le premier épaulement 26c du premier palier 26.In addition, the plastic deformation of the stator body 18 forming the first stop 33 of the first annular housing 32 of the stator body 18 ensures that the annular elastic gasket 35 is held on the first shoulder 26c of the first bearing 26.

De cette manière, le joint élastique annulaire 35 est maintenu dans le logement de retenue formé par le premier épaulement 26c du premier palier 26 bien que le premier palier 26 puisse se déplacer à l'intérieur du premier logement annulaire 32 du corps de stator 18 entre les première et deuxième butées 33, 34 suivant une direction axiale.In this way, the annular elastic seal 35 is held in the retaining recess formed by the first shoulder 26c of the first bearing 26 although the first bearing 26 can move within the first annular housing 32 of the stator body 18 between the first and second stops 33, 34 in an axial direction.

Avantageusement, l'ensemble des zones de déformation 40 est réalisé en même temps.Advantageously, all the deformation zones 40 are produced at the same time.

Ainsi, la déformation plastique du corps de stator 18 est obtenue au moyen d'un outil écrasant localement de la matière du corps de stator 18 de manière simultanée au niveau de plusieurs zones de déformation 40. Chaque zone de déformation 40 est obtenue par un poinçon respectif.Thus, the plastic deformation of the stator body 18 is obtained by means of a tool that locally crushes the material of the stator body 18 simultaneously with the level of several deformation zones 40. Each deformation zone 40 is obtained by a respective punch.

De cette manière, la première butée 33 du premier logement annulaire 32 du corps de stator 18 est réalisée de manière simple, rapide et peu onéreuse.In this way, the first stop 33 of the first annular housing 32 of the stator body 18 is made simply, quickly and inexpensively.

Préférentiellement, la première butée 33 du logement annulaire 32 du corps de stator 18 coopère avec le deuxième épaulement 26d du premier palier 26.Preferably, the first stop 33 of the annular housing 32 of the stator body 18 cooperates with the second shoulder 26d of the first bearing 26.

Dans un mode de réalisation non illustré, un deuxième joint élastique annulaire peut être disposé entre la première butée 33 du premier logement annulaire 32 du corps de stator 18 et le deuxième épaulement 26d du premier palier 26.In a non-illustrated embodiment, a second annular elastic seal may be disposed between the first stop 33 of the first annular housing 32 of the stator body 18 and the second shoulder 26d of the first bearing 26.

Ainsi, l'ajout d'un deuxième joint élastique annulaire autour du premier palier 26, en particulier entre la première butée 33 du premier logement annulaire 32 du corps de stator 18 et le deuxième épaulement 26d du premier palier 26, permet d'améliorer l'amortissement de vibrations entre la première extrémité 24a de l'arbre de rotor 24 et le stator 14.Thus, the addition of a second annular elastic seal around the first bearing 26, in particular between the first stop 33 of the first annular housing 32 of the stator body 18 and the second shoulder 26d of the first bearing 26, makes it possible to improve the vibration damping between the first end 24a of the rotor shaft 24 and the stator 14.

Dans un tel cas, la première butée 33 du logement annulaire 32 du corps de stator 18 peut coopérer avec la deuxième face d'extrémité 26b du premier palier 26.In such a case, the first stop 33 of the annular housing 32 of the stator body 18 can cooperate with the second end face 26b of the first bearing 26.

Avantageusement, la deuxième butée 34 du premier logement annulaire 32 du corps de stator 18 est formée par une paroi d'extrémité du premier logement annulaire 32 du corps de stator 18.Advantageously, the second stop 34 of the first annular housing 32 of the stator body 18 is formed by an end wall of the first annular housing 32 of the stator body 18.

Préférentiellement, le premier palier 26 comprend au moins un élément de positionnement angulaire 37 coopérant avec une encoche 38 du corps de stator 18.Preferably, the first bearing 26 comprises at least one angular positioning element 37 cooperating with a notch 38 of the stator body 18.

Ainsi, le premier palier 26 est bloqué en rotation par rapport au corps de stator 18 de sorte à ne pas être entraîné en rotation avec l'arbre de rotor 24.Thus, the first bearing 26 is locked in rotation relative to the stator body 18 so as not to be rotated with the rotor shaft 24.

Ici, et tel qu'illustré à la figure 6, le premier palier 26 comprend deux éléments de positionnement angulaire 37 coopérant respectivement avec une encoche 38 du corps de stator 18.Here, and as illustrated in figure 6 the first bearing 26 comprises two angular positioning elements 37 cooperating respectively with a notch 38 of the stator body 18.

En particulier, le deuxième palier peut être un palier lisse.In particular, the second bearing can be a plain bearing.
